Hello, Louisa Maud,
When you call up the first list of the names you are interested in, look at the LH column, most are Households but here & there Institution shows, so they do show them. I did see a note somewhere that it is difficult for some Institutions due to the amount of patients or inmates. If it is an unusual name you are looking for, it may have been mistrasncribed or you may have to wait until later in the year when the Enumerator's schedules will be available.
